For a Proto DataStore you have to use updateData() https://developer.android.com/topic/libraries/architecture/datastore#proto-write

I implemented a Proto DataStore recently following this tutorial and using Wire as an alternative to Google's codegen for Protocall buffers https://blog.stylingandroid.com/datastore-basics/
